COMBINED FIRE AND EMERGENCY ALARM.

Application filed July 17,

T 0 all to 710m it may concern:

Be it known that we, Ami-run A. TAYLOR and HENRY J. Sorni'rz, citizens of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in a Combined Fire and Emergency Alarm, of which the following is a specification.

This invention relates to a combined fire and emergency alarm adapted particularly for use in banks or similar institutions Where robberies are liable to occur, and as a safeguard against destruction by fire; The invention includes an electrical switch having a pivotally mounted armature operating as a latch under control of a spring, said armature being normally maintained in open relation with reference to the switch by a resiliently mounted rock-lever operating as a catch, links being connected with the rock-lever tor controlling one of its movements and manually operated push-bars being provided for use in cases of emergency, for moving the links torelease the rock-lever from the armature, whereby the latter may move to effect a closure of the switch for ringing an alarm bell, an arrangement of parts being provided for automatically ringing the alarm bell in the event of a fire. Since the device consists of few and simple parts it may be economically manufactured, and itprovides anarticle useful for a variety of purposes other than those specifically mentioned.

In the accompanying drawing, Fig. 1 is a plan view of the device. Fig. 2 is a partly broken, sectional view through the support on line 22 of Fig. 1. Fig. 3 is a side view of the support when inverted, the roller shown in Fig. 2 being dispensed with. I

.Beferring now to the drawing, numeral t indicates a support which may have any suitable size or proportion. At 5 is indicated a switchb1ock which is stationary with the support, an electrical switch being provided for said block, consisting of an electrical contact-piece 6 provided with an electrical conductor '7 and an electrical contact-piece 8 provided with an electrical conductor 9., said conductors T and 9 being energized by any suitable means and arranged for ringing a bell 10 when an electrical circuit is established by a metallic bar or latch 11 which is pivotally mounted, as indicated at 12, upon the electrical contact-piece 6, and when tree 1920. steam. 397,067.

to swing it will engage the electrical contact piece 8 by means of a spring 13 which is mounted'at one of its ends upon the end or" member 11, its opposite end being secured to the support.

Numeral 1% indicates a rock-lever which is disposed inclinedly and is pivotally mounted at one of its ends upon a bracket 15 which is secured to the support, said lever being provided with a notch 16, between its ends, and at 17 is indicated a spring having one of its ends mounted upon the rock-lever, its opposite end being secured to the support.

At 18 is indicated a pull-rod, and it will be understood that an operator, by manual use of said rod may cause a horizontal swingingmovement of member 11 to cause it to move in a direction of the notch 16 against the force ofthe spring 13, the parts being of such proportion that member 11, while swinging outwardly, will engage and slide upon the inclined rock-lever and will enter the notch .16, said lever 14 having a swinging movement against the force of the spring 17, the notch 16 operating asa catch. At 50 is indicated a standard which is mounted on the support, operating to limit the outward swinging movement 0]": said member 11, and the'latter will remain in engagement with the catch or notch 16 until the lever 14 has been swung outwardly against the force of its spring 17. i

Numeral 19 indicates a push-bar which is disposed approximately at right-angles to the lever 14 and is pivotally connected there with as indicated at CL, said bar 19 extending outwardly of the support and being provided. with athumb-piece Z). Numera 20 1ndicates a push-bar having a pivotal mount ing for its inner end upon a link 21, said push-bar being disposed at right-angles to the bar 19 and being slidably mounted in an upright part c of the support to extend outwardly, its free end being provided with a thumb-piece cZ. Numeral 22 indicates a link cooperating with the link 21 for a control of one of the movements of the rock lever, said links being pivotally connected at their inner ends as indicated at e, the link 21 having a pivotal connection with a bracket 23 which is secured to the support, and the the link 22 being pivotally connected with the end of the rock-lever, as indicated at f. As thus described the device may have a variety of uses. It the bar 20 is pressed inwardly while member 11 is in engagement trical contact-piece 8 by force of the spring with the catch 16, this movement will obviously cause the links 21 and 22 to be swung inwardy, the result being that the rock-lever 14 will be swung outwardly from member 11 for a release of the latter from the catch 16, and member 11 will immediately move into engagement with the elec- 13 for completing the electrical circuit. Numeral 24 indicates a horizontal detent-arm which is secured to the support and is disposed in the plane of movement of the lever 14; to limit the swinging movement of said lever, caused by operation of the spring 17. Also if the bar 19 is pushed inwardly, the lever 14 will have a similar movement to that last described, with a like result.

It will be seen that the device provides means for the ringing of a call-bell or alarmbell by moving either push-bar mentioned, the movements of said bars being at rightangles with reference to each other, the pressure of the bar 19 being upward when the parts are disposed as shown in Fig. 2, and the pressure being downward when disposed as shown in Fig. 3. The device is particularly useful in banks to call assistance in case of daylight robbery or -liold-ups and on this account push-bars are arranged to be moved vertically as well as horizontally, these positions being of importance so that they will beaccessible in case of emergency.

The arrangement of parts provides for automatically ringing an alarm in case of fire. Numeral 25 indicates a weight to which is attached a fuse 26, the latter being supported by a bracket 27 which is secured to the support, and it will be seen that if the fuse is weakened in a sufiicient degree by heat, or is materially injured by fire, the

weight will be released, the result being that a rod 28 which is connected with the link 21, will be moved outwardly and will cause the link 21 to swing in a manner to move the lever 14- to release member 11 from the catch 16, which will obviously cause ringing what we claim and desire to secure by Letters Patent is,

Electrical switch operating means, comprising, in combination with a support,-an electrical contact-plate and a second electrical contact-plate stationary with the support, a pivotally mounted armature in electrical communication with the first contactplate and provided with a spring to normally maintain the armature in electrical communication with the second contact-plate, a resiliently mounted rock-lever provided with a catch, a pull-rod for moving the armature into engagement with the catch to terminate the electrical communication of said armature with said second electrical contact-plate, a plurality of links connecting the rock-lever with the support, an operating-rod connected with the rock-lever, operating rods connected with one of said links, said operating-rods being movable for releasing the armature from the catch to permit electrical communication of the armature with said second contact-plate.

In testimony whereof,we have afiiXed our signatures in presence of two witnesses.
